mjorbit: open-source space robotics simulator runs thousands of parallel worlds on one GPU
ChongZzZhang · x · 2026-11-05
Developer johnzhangx released mjorbit, an open-source simulator for space robotics that runs thousands of parallel worlds on a single GPU for RL training.
In the demo, a single RL policy trained entirely in mjorbit approaches from kilometers away in LEO, grabs a satellite with both arms, and points it toward Earth. A detailed thread accompanies the release — relevant for anyone working on sim training, sim2real, or on-orbit servicing.
